Shaving Cream in a Vacuum

Buy Add to Lightbox Download
Shaving cream is placed in a vacuum chamber and the air is removed.  As the air is removed the pressure drops causing the air trapped in the shaving cream to expand.  The trapped air expands to many times it's original volume before the bubbles burst.  This image is part of a series taken at different vacuum pressures.
